Question

About how many times larger is the diameter of the Milky Way Galaxy than the diameter of Saturn’s rings? (Data: Saturn’s rings are about 270,000 km in diameter; the Milky Way is 100,000 light-years in diameter.)

Answer 1

Answer:

The diameter of the Milky Way is 3,503,974,249,104 km times larger than the diameter of Saturn's rings.

Explanation:

1 light year is the distance light can travel in one year. One light year is equal to exactly to 9,460,730,472,580.8 km.

Therefore the diameter of the milky way in distance is 9,460,730,472,580.8 x $10^{5}$km while the diameter of Saturn rings are about 270,000km.

Comparing both diameters

$\frac{9,460,730,472,580.8 * 10^{5}}{27*10^{4} }$

= $350397424910.4 * 10^{1}$

= 3,503,974,249,104 km
